Application fi1ed November 16, 1912. Serial No. 731,853.

To all whom it may concern:

Be it known that I, CLARENCE ARNOLD F ELL, subject of the King of GreatBritain and Ireland, residing at Fanshaw House, Dronfield, county ofDerby, England, consulting engineer, have invented certain new anduseful Improvements in Shovels for Stokers Use and other Purposes, (forwhich I have obtained Letters Patent in Great Britain, No. 942, filedJanuary 12, 1912,) of which the following is a specification, referencebeing had to the accompanying drawing.

This invention relates to an improvement applicable to shovels for theuse of stokers. for the more effective spreading of coal in firing, butit may be also used for spreading grain and the like.

The invention consists in the combination with or the addition to theface of shovel, of a number of radially arranged longitudinal ribsrising from the face of the blade, or if preferred similarly arrangedgrooves or hollows may be substituted.

The invention is shown on the annexed sheet of drawings.

Figure 1, represents a front elevation of stokers shovel made with ribsaccording to this invention. Fig. 2, is a side elevation of same. Fig.3, is a separately made plate for attachment to a shovel. Fig. 4, edgeview of grooves or hollows in place of ribs. Fig. 5, two views ofseparately made ribs, either by casting, rolling or stamping for repairsand the like.

The object of these radial ribs (or grooves) is to cause the coal todivide or separate during its forward movement in stoking, and to leavethe shovel in streams having a tendency to radiate or spread laterally.Thus small coal delivered from. a shovel constructed with this inventionwould be spread over the surface of the fire grate more equally thanhitherto, dispensing with the usual subsequent process of raking, (whichrequires the furnace door to be open and admit cold air) which isobjectionable,

Referring to the drawings, A are the ribs arranged radially and eitherintegral therewith and produced by stamping the plate 13 between top andbottom dies, or made upon a separate plate D Fig. 3, and afterwardattached to a shovel plate, or they may be made separately by casting,stamping or rolling in continuous strings or lengths, as Fig. 5. Asclearly shown all of the ribs radiate from a common point on the centrallongitudinal axis of the body portion of the shovel. The dimensions maybe varied, but (for example only) it is found that six inches long andthree quarters of an inch high give a good result upon an ordinary sizeof shovel. The front of each rib is inclined backward or toward the rearto enable the shovel to more readily take up the coal and the ribs areinclined downwardly toward the rear of the body portion of the shovel.

Preferably the face of the shovel plate is shaped to incline upward fromeach side to the center or coffer C, as indicated by the dotted line0000 Fig. 1.

When the ribs are made upon separate plates as Fig. 3, such plat-es maybe used for repairing worn shovels or they may be secured upon newshovels which are made without ribs.

A shovel made according to this invention will spread the coal acrossthe furnace without any twisting action of the stokers arms.

I am aware that shovel blades have been corrugated and embossed forstrengthening and for ornamenting them. Also that a single rib inclinedin opposite directions extending from the center across the blade to itssides has been previously proposed, and I make no claim to such, but

What I desire to claim, is

1. A shovel comprising a body portion provided with a plurality oflongitudinally extending radially disposed shallow ribs, all of saidribs radiating from a common point on the central longitudinal axis ofsaid body portion.

2. A shovel comprising a body portion provided with a plurality oflongitudinally extending radially disposed shallow ribs, all of saidribs radiating from a common point on the central longitudinal axis ofsaid body portion, each of said ribs being spaced from the ribs adjacentthereto throughout its entire length.

3. A shovel comprising a body portion provided with a plurality oflongitudinally extending radially disposed shallow ribs, all of saidribs radiating from a common point on the central longitudinal axis ofsaid body portion, each of said ribs being spaced from the ribs adjacentthereto throughout its entire length, the length of said ribs being lessthan the length of the said body portion and each of the ends of each ofsaid ribs beportion said ribs being inclined downing spaced from theends of said body por- Wardly toward the rear of said body portion. 10
